Answer:
y intercept (0;4)
Step-by-step explanation:
let x = 0 because the graph will intersect the y-axis at the value of 0 for the x-axis
Option B: 1.6 s.
Although the equation is not included, you can obtain it by physical considerations
H(t) = -16.t^2 + 52t + 16
The maximum point is at the vertex and the vertex is in the middle of the roots.
The roots are when H(t) = 0,
So you have to solve 0 =-16t^2 + 52t + 16
Use the quadratic formula and you will find t = 3.53 and t =-0.28
Then the vertex is at the middle point = (3.53 -.028)/2 =1.63 s and the answer is option B: 1.6 s.
Answer:
El limite de velocidad es
Step-by-step explanation:
Para determinar el limite de velocidad en unidades de km/h es necesario hacer una conversión, esto se puede lograr al aplicar una sencilla regla de tres:
⇒ ⇒
Nota que para poder hacer la conversión es necesario saber a cuanto equivale 1 milla en kilometros (1Mi = 1.6093 km).
Por lo tanto, el limite de velocidad es de
In converting a decimal to a percent you just need to multiply it by 100.
Solution on the problem above:
3.45 x 100 = 345%
Therefore the answer is letter A.
It will be vice versa in converting percent to decimal. You just need to divide it by 100.
For example, we convert the 345% to decimal:
345%/100 = 3.45
